Sig Sauer MCX rifle 5.56 first impressions

In General

Sig Sauer MCX rifle first impressions, chambered in 5.56.
Fired 100 rounds of .223 and 5.56 with zero malfunctions. I like the keymod handguard, and will mount a Surefire on it. The interchangeable barrels are awesome, and you can go from 5.56 to 300 blackout to 7.62 x 39 !
